Kiwi Property has secured Farmers for its proposed Galleria Sylvia Park mall expansion, due to be completed in 2020.
Farmers has agreed to lease the 8000sq m of space to create a new two-level department store.
Chris Gudgeon, chief executive of Kiwi Property, said shoppers had been asking for a Farmers store to open at Sylvia Park.
"Farmers is an iconic and much-loved New Zealand brand and a perfect fit for our expansion plans for the centre, which could comprise up to 20,000sq m of additional retail space," Gudgeon said.
Kiwi Property was planning to be in a position to give the green light to its Galleria expansion project by mid-2018, following board approval.
